Cyril Cayron

Mes recherches: J'ai travaillé comme microscopiste/cristallographe/métallurgiste sur des projets très variés comme les aciers pour le nucléaire, les alliages titane et nickel pour l'aéronautique, les interconnections en cuivre pour la microélectronique, les piles à combustible haute et basse température, le silicium photovoltaïque hétérojonction et monolike, les batteries au lithium à base de LiFePO4 et silicium. Derrière la plupart de ces sujets de recherche appliquée se cachent des problèmes de recherche fondamentale comme celui lié aux transformations de phases. J'ai donc été amené à travailler sur ce sujet passionnant et j'ai pu démontrer que les variants cristallographiques générés par des transitions structurales forment une structure algébrique de groupoïde. Ces travaux ont mené au développement du logiciel de reconstruction des grains parents à partir de données EBSD appelé ARPGE et distribué dans plus de 20 pays. En 2013-2015 j'ai proposé un nouveau modèle cristallographique pour les transformations martensitiques fcc-bcc dans les aciers, comme une alternative à la théorie phénoménologique de la transformation martensitique. Ce modèle a été depuis étendu aux transformations fcc-hcp (type cobalt), bcc-hcp (type titane) et bcc-fcc (type laiton), ainsi qu’à differents modes de maclage mécanique dans les métaux fcc et hcp. Ce modèle à sphères dures montre que la transformation implique une «distorsion angulaire», forme plus générale que le cisaillement. Le modèle prévoit la possibilité que le plan d’interface de certaines macles mécaniques ne soit pas un plan invariant. Un tel cas de maclage « exotique » a été observé expérimentalement par EBSD en 2017 dans un monocristal de magnésium pur. Je travaille maintenant à définir de manière algébrique les concepts de variants (orientation, distortion, correspondance), et sur les types de macles mécaniques (I, II, et d'autres oubliés des théoriques classiques). Mon parcours : 2014-maintenant: Collaborateur scientifique à l'EPFL/LMTM, Neuchâtel, Suisse. J'aide le professeur Roland Logé dans ses travaux de recherche sur les liens entre les fortes déformations, les textures, les tailles de grains et les transformations de phases (diffusives et displacives). Je suis en charge de la salle de métallographie et des caractérisations SEM, EDS, EBSD, TEM, HRTEM. Je codirige trois thèses (Annick Baur, Margaux Larcher, Céline Guidoux). Je suis reviewer pour Acta Mater., Scripta Mater., Acta Cryst., J. Appl. Cryst., Mater. Charact., etc. 2000-2014: Ingénieur de recherche et responsable du groupe Nanocaractérisation, CEA/LITEN, Grenoble, France. 2012 : Habilitation à Diriger des Recherches (HDR). 1996-2000: Thèse sur l'étude par microscopie électronique de composites à matrice aluminium. Directeur de thèse Philippe Buffat, CIME, EPFL, Lausanne, Suisse. J'ai pu montrer un lien cristallographique entre différentes phases des alliages 2xxx et 6xxx et proposer pour la première fois une structure complète pour la phase beta prime des nanoprécipités. 1995-1996: Scientifique du contingent, travail sur les écrans électrochromes, COGIDEV, Rueil-Malmaison, France, fondé par M. André Giraud, ancien ministre de la défense et ancien ministre de l’industrie. 1992-1995: Ecole Nationale Supérieure des Mines de Nancy, France

Kurt Schenk

Pramod Rastogi

He received his MSc degree from the University of Lucknow, MTech degree from the Indian Institute of Technology Delhi, and doctorate degree from the University of Franche Comté in France. His research activities are principally in the area of holographic interferometry, speckle metrology, fiber optics sensors, phase shifting and moiré. He is the author or coauthor of more than 175 scientific papers of which more than 140 are published in peer-reviewed archival journals. He is also the author of book chapters, Encyclopaedia articles, and has edited several books in the field of optical metrology. His guest-edited three special sections on Optics in Switzerland for Optical Engineering in 1995 are even today an invaluable source of reference relative to optical engineering activities in Switzerland both at the academic and industrial levels. He has guest-edited over a dozen special dedicated issues in archival journals. He has also chaired and organized several international symposiums, such as, the International Conference on Applied Optical Metrology, Balatonfüred, Hungary, June 8-11, 1998; or the Conference on Trends in Optical Non-destructive Testing, Lugano, Switzerland, May 2-5, 2000, or the Conference on Advanced Phase Measurement Methods in Optics and Imaging, Monte Verita, Ascona, Switzerland, May 16-21, 2010 etc. He is a Fellow of the Optical Society of America (1993) and a Fellow of the Society of the Photo-Optical Instrumentation Engineers (1995). He is also a recipient of the Hetényi Award for the most significant research paper published in Experimental Mechanics in the year 1982. He was Elected as a Member of the Swiss Academy of Engineering Sciences (SATW) in 2014. He was recipient of the SPIE Dennis Gabor Award, 2014. The Dennis Gabor award is presented annually in recognition of outstanding accomplishments in diffractive wave front technologies, especially those which further the development of holography and metrology applications. He was an honorary visiting Professor at the IIT Delhi between 1999 & 2003. Since 2000 he has also been active in laying groundwork for collaboration with the Indian Institutes of science and technology. Between the years 2000 & 2004, he was doing this as a part of his broader activity as in-charge of relations with Asia. His initiatives have led to academic exchange programs involving faculty and students with a view to fostering networking, research linkages and partnerships. To cite a few of his many initiatives: his active contribution to the holding of a high level Indo Swiss Workshop on Science & Technology at Bangalore in 2003; the setting up of ISJRP - the pilot project on bilateral partnership in S&T between Switzerland and India - in 2004; developing ISBRI (Indo-Swiss bilateral research initiative) in 2006; etc. He remained as the main coordinator of the Indo-Swiss Joint Research Program between the period covering the program's inception in 2004 until February 2011. He is currently responsible for developing academic and institutional relations with the universities in India and South-East Asian countries. He has been instrumental in helping to open up a range of opportunities to the EPFL students, such as, doing their "mobility" years at one of the IITs or, their final year major projects or internships at one of the Indian institutions/companies. Over a hundred EPFL students have benefited from these programs. He was instrumental in establishing Internship program with the aim of promoting an awareness of EPFL among the IIT students. This program has become very popular among the IIT and IIITA students with several hundreds of them having benefited from this program. He played a key role in the setting up of the EPFL-IIT Madras joint postgraduate course on "Technology and sustainable development" in 2000-01. He was the co-director of the last edition of the course which was held between January and April, 2008.

Pierre Magistretti

Pierre J. Magistretti is an internationally-recognized neuroscientist who has made significant contributions in the field of brain energy metabolism. His group has discovered some of the cellular and molecular mechanisms that underlie the coupling between neuronal activity and energy consumption by the brain. This work has considerable ramifications for the understanding of the origin of the signals detected with the current functional brain imaging techniques used in neurological and psychiatric research (see for example Magistretti et al, Science, 283: 496 497, 1999). He is the author of over 100 articles published in peer-reviewed journals. He has given over 80 invited lectures at international meetings or at universities in Europe and North America, including the 2000 Talairach Lecture at the Functional Mapping of the Human Brain Conference. In November 2000 he has been a Mc Donnel Visiting Scholar at Washington University School of Medicine. Pierre J. Magistretti is the President-Elect (2002 2004) of the Federation of European Neuroscience Societies (FENS) which has a membership of over 15000 European neuroscientists. He has been first president of the Swiss Society for Neuroscience (1997-1999) and the first Chairman of the Department of Neurosciences of the University of Lausanne (1996 1998). Pierre J.
